4. CLIENT
 A device that gets the service offered by server
 Generally classified as,
Fat client :
•A rich client or thick client, is a client that performs the bulk of
any data processing operations itself, and does not rely on the
server
•Delphi, Net Beans and Visual Studio.
Thin client :
•Uses resources of host computer
•Minimal sort of client
•JavaScript, ASP.NET, JSP, Ruby

13. MAIL SERVER
 Computerized equivalent of your friendly neighborhood
mailman.
 Every email that is sent passes through a series of mail servers
along its way to its intended recipient
 2 main categories: outgoing mail servers and incoming mail
servers.
 Outgoing mail servers are known as SMTP.
 Incoming mail servers come in two main varieties.
POP3, or Post Office Protocol, version 3, best known for
storing sent and received messages on PCs' local hard
drives.
IMAP, or Internet Message Access Protocol,always store
copies of messages on server.

Momentum
APACHE JAMES
 Java Apache Mail Enterprise is an open source SMTP and POP3 mail transfer
agent and NNTP news server
 Defines matchers and mailets and allow users to write their own mail-
handling code
 A matcher is used to classify messages based on some criteria, and then
determines whether the message should be passed to an appropriate mailet for
processing.

computers
 Database management systems frequently provide database
server functionality.
 Accessed through a "front end" running on the user’s computer

packetized, addressed, transmitted, routed and received at the destination
Key principles are : End-to-end connectivity, Robustness Principle
Functionality is organized into four abstraction layers
Link layer, containing communication technologies for a single network
segment (link)
Internet layer, connecting hosts across independent networks, thus
establishing internetworking
Transport layer handling host-to-host communication
Application layer, which provides process-to-process application data exchange.

12/24/15 23

24. HTTP
Hypertext transfer protocol (HTTP) is an application protocol for
distributed, collaborative, hypermedia information systems
Functions as a request
A web browser-the client
An application running on a computer hosting a web site - server.
Client submits an http request message to the server.
The server, which provides resources such as html files and other
content, or performs other functions on behalf of the client, returns a
response message to the client
12/24/15 24

25. OTHER PROTOCOLS
Simple Service Discovery Protocol (SSDP) is a network protocol for
advertisement and discovery of network services
The Dynamic Host Configuration Protocol (DHCP) is a standardized network
protocol used on Internet Protocol (IP) networks for dynamically distributing
network configuration parameters, such as IP addresses for interfaces and services
Simple Network Management Protocol (SNMP) is an Internet-standard protocol
for managing devices on IP networks.
 Devices that typically support SNMP include routers, switches, servers,
workstations, printers, modem racks and more.
SNMP is widely used in network management systems to monitor network-
attached devices for conditions that warrant administrative attention
